nautilus locking on cdrom w/ large file count

[Micha Feigin <michf@math.tau.ac.il>]

I have a cd with 600+ files on it.
I tried to mount it using both ide interface and ide-scsi interface (its
a burner).
After opening it with nautilus I can't umount it with a message that the
device is busy.
When I try to use the force flag for umount I get the following message:
umount2: Device or resource busy
umount: /dev/hdc: not mounted
umount: /mnt/tmp: Illegal seek
nautilus takes a very long time to read all the files, and has a lot of
trouble going past the 300 file mark, although I am not sure if its
nautilus' fault.
Anyone else having the same experience or an idea for a solution?

I am using kernel 2.6.0-test1
